IMPROVEMENT IN SHIPS LANTERNS.

Specication forming part of Letters Patent N o. 159,933, dated February16, 1875 g application filed January 30, 1874.

To all whom it may concern:

Be it known that I, FREDERICK J. KENNY, of Boston, Massachusetts, haveinvented Improvements in Ships7 Lanterns, of which the following is aspeciiication:

This invention relates to the signal or side lights of ships. Itconsists, rst, in conning the segmental lens on the putty-bed, by meansot' bands fastened with nuts; second, in providing the door at top andbottom with peculiarly-shaped bolts or hooks, adapted to be shut intosuitably-arranged staples.

Figure l is a front elevation. Fig. 2 is an elevation of the door ends,with the door open, and the interior construction shown. Fig. 3 is asectional plan. Fig. 4t is a vertical section.

A is the glassa segmental Fresnel cylindrical lens-iiuted on its outersurface in the central belt, as shown at a. This intensifies thebrilliancy of the light. This glass is tted into the recess made for it,which is beveled in from the front of the lamp-box, as shown at E, Figs.3 and 4. A ilange, j', is turned upon the metal forming the sides of therecess, to form the retaining-sash for the putty. Putty, white-lead, orother suitable plastic material is then put into the angle between thebevel E and angef, and the lens bedded like a light of glass. Thus farthe usual process of setting the glass has been followed. The presentmethod next requires that a strip of sheet metal should be soldered tothe bevel E at top and bottom, pressing the glass, and binding it. Inlien of this, I pierce the beveled sides of the recess with holes g,Fig. l, near the top and bottom, and pass a bent rod, c, with a knob atone end and a screw at the other, through them outside the glass, andset up the nut d, drawing'L the rod tight to the glass. If desirable,the rod may be clad with rubber. The door j shuts into a recess, h, theinner edges of which are beaded, as shown at K, Fig. 2. In forming thisbead, the sheet metal is merely turned outward and backward on itself,and is compressed strongly on a strip of rubber, Z, on each side and atthe top of recess h. This springs the rubber strip up from the face ofthe recess at a small angle, and on shutting the door the rubberltouches the door, and seals the crevice airtight. This door is locked bya bolt, much like the ordinary tinners7 bolt, but an improvement whichlocks the door at top and bottom. Two staples, m m, furnish the slideson the edge ofthe door. The long bar passing through them has a knob orhandle at the center, a hook, u, at the top, and a shot-bolt, n, at thebottom, each bent at an angle, to constantly draw, wedge, and hold thedoor tightly against the rubber strip when shut into the staples o.

vBy confining the door top and bottom, it will nary workman or sailor,and do not increase the cost.

I claim and desire to secure by Letters Patent- 1. The combination ofthe segmental lens A with the recess, having beveled sides E, and withthe curved rods c and nuts d, as and for the purposes set forth.

2. In a lantern, the combination of the door j, the staples m, and thebolt, with hook n and bolt n", bent at an angle, to constantly draw,Wedge, and hold the door, when shut into the staples o, for the purposeset forth, substantially as described.
